WHY THE HELL DO YOU THINK THESE CANNING COMPANIES HAVE GONE TO PULL TOP CANS? THEY JUST WON'T KEEP AS LONG AS COMPLETELY SEALED CANS.

I might be willing to concede that the pull top seals might not last 40 years, but sealed is sealed. The pull top is not any more or less sealed than the key and strip model of the past, and the can opener style can that came before that. I'll set one aside and let you know in 40 years.

Mark it on your callendar and come back here December 20, 2052. Unless it all ends tomorrow. In which case I'll be pissed I bought all that fucking Spam.
